Creating a new D&D world, part 12

I recently purchased The Ultimate RPG Game Master's Worldbuilding Guide: Prompts and Activities to Create and Customize Your Own Game World by James D'Amato and it, and going whale watching, inspired me to create a new D&D world. So here we go! I'm going to use prompts from the book to begin crafting this world, but not all posts will be from there.

You can read part 1 of my planning here, read part 2 of my planning here, read part 3 of my planning here, read part 4 of my planning here, read part 5 of my planning here, read part 6 of my planning here, read part 7 of my planning here, read part 8 of my planning here, read part 9 of my planning here, read part 10 of my planning here, and read part 11 of my planning here. 

These are the gods of the world, modified from the list on page 57. I will try and describe all that I selected. Note though that I organized them into categories myself. Also note that Speir, Talamh, Uisce, and Tine are quadruplets and this pantheon does not have incest. Finally, the gods live in an Olympus-like realm.
